Capacities For AUDI A6 (4F_) From My 2005

WARNING: This page does not describe the selected car, but rather 19 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Also applies to the Audi S 6 and the Audi RS 6.

Features of the refrigerant system:

Restrictor
Reservoir
"Denso" A/C compressor with A/C Compressor Regulator Valve -N280-. Refer to REFRIGERANT CIRCUIT R134a

The compressor installed at the factory for a 10-cylinder TFSI engine (Audi R S6) has a smaller quantity of refrigerant oil (70± 10 cm ) than the compressor for the 10-cylinder FSI engine (Audi S 6) and other engines (130 ± 10 cm ) due to the different testing procedures for the engines (the compressors at present differ only in part number and quantity of refrigerant oil, see also the A/C compressor data plate). When adjusting the total oil quantity in the refrigerant circuit for a 10-cylinder TFSI engine (Audi RS 6) at the factory, the oil quantity that was reduced in the compressor (60 ± 10 cm ), has to be filled somewhere else in the refrigerant circuit. This is not necessary during servicing, since the replacement A/C compressor is delivered with the original oil fill capacity (130 ± 10 cm ) (it would only be necessary during servicing if a new A/C compressor with a lower oil capacity was being installed). Refer to the parts information.

NOTE:

The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. On A/C compressor replacement, the quantity of oil in the A/C compressor is therefore to be adjusted.

The Audi A6 are equipped with different A/C compressors depending on engine and production period.

This A/C compressor is available as replacement parts with different versions therefore note the exact part number. Refer to the REFRIGERANT CIRCUIT R134a

A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
